Description

Building photovoltaic integrated annular roof system Technical Field The utility model relates to the technical field of building photovoltaics, in particular to a building photovoltaic integrated annular roof system. Background With the deep fusion of information technology and industrial development, the construction industry is coming from an unprecedented revolution. Future buildings are not simply living or working spaces, but are becoming small ecological systems, and the functions of self-sufficient power supply, water circulation and the like, such as high-efficiency energy utilization and environmental friendliness are realized. After the goals of "carbon peak, carbon neutralization" are put forward, the industry of all nationwide industries has raised the hot trend of green development, and various green buildings and ultra-low energy consumption buildings are considered as the development direction of the building in the future in recent years. In a series of green building concepts, building photovoltaic integration (BIPV) is a popular concept crossing two industries of building and new energy, and is prepared to be touted as a popular topic in the fields of building and new energy. The distributed photovoltaic power generation is flexibly and efficiently supplied by power, is commonly arranged on idle roofs of houses, enterprises and public institutions, industrial and commercial buildings and other places, and becomes an important force for energy conversion in China. In early days, the distributed photovoltaic power generation mainly adopts the traditional BAPV technology, namely a solar photovoltaic power generation system is added on a building, for example, a common metal roof is provided with a photovoltaic module after a special fixture and a profile bracket matched with the photovoltaic system are added on the metal roof, the fixture adopted by the method can limit the deformation quantity of the metal roof caused by thermal expansion and cold contraction, the probability of tearing of the metal roof at the fixture is increased, and hidden danger of water leakage occurs. However, with the advent of BIPV technology, this situation has changed, and the special jigs and profile brackets can be omitted entirely, and the photovoltaic modules can be "integrated" directly onto the metal roof panels. BIPV technology has successfully replaced BAPV with its aesthetic, safety and cost advantages and is becoming the mainstream. However, as the demand for building functions and building appearances increases, more and more large commercial building roofs are designed in a ring shape, and when a metal roof plate is used as a waterproof structure layer, the metal roof plate needs to be a profiled plate, i.e., a "big-and-small-head" roof plate. The board end near the roof center area is a 'small end' board end, the board end near the outer wall area is a 'big end' board end, the shape of the main stream photovoltaic module is rectangular in the current photovoltaic module market, the main stream photovoltaic module cannot be matched with the special-shaped metal roof board of the annular roof, the photovoltaic module can be paved only after a special fixture and a special-shaped material bracket are added, and the annular roof building cannot keep up with the pace of building photovoltaic integration times development.
